SPECIFICATION forming part of Letters Patent No. 394,609, dated December 18, 1888.

Application filed March 31, 1888.

T0 at whom, it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Nail Making, Distributing, and Driving Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

It is very essential for certain kinds of naildriving machines that there be provision for supplying nails very rapidly. This is particularly necessary in connection with heelblank compressing and loading, heel-blankloading, and heel-blank-attachiug machines. Machines of this character can be operated to use a large number of nails per minute, and it is desirable that the nails be made, distributed, and delivered as quickly or as rapidly as they can be driven. In work of this class it is often necessary to drive from twenty to thirty in a gang or group, and if the production and feeding of the nails can be increased to approximate the rapidity of action of the nailing-machine as many as fifteen to thirty gangs can be driven in a minute. This would require the production and distribution of a very large number of nails, and for this reason it is necessary that a nail making and distributing mechanism be simple, not liable to get out of order easily, and that there be as few transfers of the nails as possible. To accomplish this result, I have orgai'lized a machine which is in some respects like mechanism heretofore described in various of my applications and patents, but which varies from them in two important particulars: First, the machine is organized to make nails from as many wires as there are nails in the gang or group which it is desired to distribute and drive. For instance, suppose the gang of nails to be driven should consist of thirty. The machine would then be organized to make and deliver nails from the ends of thirty wires, and this organization provides that the machine shall make but one revolution for every gang of thirty nails made and delivered. Sec- 0nd, it also provides for the delivery of the nails directly from the nail-making devices into the distributer, instead of into an interseaa No. 269,055. (No model.)

I mediate receiving or transferring block, which has to be moved a number of times to bring its holes in line with the delivery-throats of the nail-making devices and then to bring them in register with the holes of the dis tributer. By my present construction I am enabled to dispense with this carrier or transferrer, and this not only simplifies or cheapens the machine, but removes from it an element which may interrupt (perhaps not but rarely, but still at some time interrupt) the regular action of the machine.

It is desirable, also, where so large a number of nails is made at one time to arrange the nail-making devices in relation to each other to bring the throats or passages through which they are delivered as closely together as possible. The machine is represented in the drawings as organized to make and de liver thirty nails or any less number at a time.

In the drawings, Figure l is a view in side elevation of the nail making and distributing portion of the machine having the features of my invention. Fig. 2 is a view in horizontal section upon the line .1 .r of Fig. 1. Fig. 3 is a vertical section from back to front of the machine. Fig. i is a horizontal section upon the line 1 y of Fig. I). Fig. 5 is a view in elevation of the side of the nail making and distributing devices opposite that represented in Fig. I. Fig. (3 is a plan view of the nail making and distributing mechanism. Fig. 7 is a view in front elevation of the nail making and distributing section. Fig. 8 is a detail viewillustrating the connection of the distributer with the nail-driving devices.

A represents the frame of the machine and its supports, the shafts a. a, a a a a, and a (7. These shafts arearranged in four pairs, two of which, a a and a a are upon a line below the upper pairs, a (l and a a and for convenience the pairs of rolls are arranged so that one of the upper pairs, a a, may be arranged between one roll of each of the lower pairs. (See Fig. 1.) The object of this arrangement will be made apparent later in the description.

Upon each pair of shafts there is mounted a number of nail pointing and severing devices, each of which comprises the sections 1) b of a boX pointing-die, the cut-off b and preferably the presser b These parts are like simi-' lar parts described in the Patent No. 37 5,209, dated December 20, 1887, to O. 0. Small. Each pair of shafts carries many of these pointing and severing devices as may be desired.

In the drawings I have represented the pairs to a and a (L3 as provided with .seven and the pairs a (1, ends a as having eight.

set-and each set of these cams or projections is represented as supported by a common supporting-bar I)".

(See Fig. 4.)

- Each line of nail pointing and severing devices has feeding mechanism to co-operate therewith to feed the wire to the dies and'to regulate the length of the nails, and I have represented these feeding devices as consist ing of feed-rolls c of the desired length to feed simultaneously the seven or eight wires. They have corrugated surfaces, the corrugations extending lengthwise the shaft, or their sur-' faces .may be otherwise roughened, and the pair 0' c feeds the wires to the pointing and severing devices of the shafts CL CL. The'pair c c feeds the wires to the nail pointing and severing devices of the rolls a a The pair 0 c feeds the wires to the nail pointing and severing devices of the rolls a a and the pair c c feeds the wires to the nail pointing and severing devices of the rolls a a These feeding-rolls, like the nail pointing and severing devices, are arranged upon two lines so disposed that the lower line feeds the wires to the lower line of nail pointing and severing'devices, while the upper line feeds the wires to the upper line of nail pointing and severing devices. This necessitates that the two pairs a a and a a of the lower line of nail pointing and severing devices be separated from each other sufficiently to permit the line of tubes cl, forming the passages or throats d, which receive the nails from the nail pointing and severing devices and deliver them to the distributer, to be located between them; also, that there be space for the line of wires which feeds the nail pointing and severing devices of the rolls (1, a between the two pairs of nail pointing and severing devices of the upper line; also, that the line of wires upon which the nail pointing and severing devices of the rolls a a, operate shall pass between the projections or cams b and that the line of tubes (1 having the throats or passages d, and which serve to conduct the nails from the nail pointing an d severing devices of the rolls a a shall be arranged between the cams or extensions 6. This also involves the placing of the nail pointing and severing devices of the lower rolls so that the nail pointing and severing devices of the upper rolls shall come midway between them. (See Figs. 4: and (3.) By this arrangement the throats or passages d d of the upper set of nail-makingdevices and the throats or passages d (1 formed in their respective tubes (Z (1 come quite closely together and are arranged npon parallel cross-lin es. The tubes d (l d d are supported by a cross-plate, (Z and the tubes (Z (Z additionally by cross-plates (l (Z This plate (Z has holes in continuation of the holes of the tubes and of the throats. One feed-roll of each pair is positively rotated or turned by means of a connection with one of the shafts of the nailmaking device with which it is used; and, referring to Fig. 1, it

will be seen that the roll 0 is rotated by means of a crank, 6, upon the shaft a and ratchet-wheel 6' upon the feed-roll shaft 0, a pawl, 6 carried by a lever, e, pivoted upon the end of the shaft c and connected with the crank e by means of a link or connecting rod, 0 the end of which is adjustable toward and from the end of the lever e to vary the extent of rotation of the feed-roll. The feedroll shaft 0 is connected with the shaft a of connecting the shaft a with the feed-roll, and

there are similar connections between the shaft (0 of the second of the lower pair of nailmaking devices and the feed-roll shaft 0 and between the shaft (1, of the second pair of upper nail-making devices with the feed-roll shaft 0 The distributer comprises a number of tubes, F, having conducting-passages f, and the upper ends of which, preferably, are held in proper relation to each other and to the throats d (1 cl (1 by a plate, f, the lower ends of the tubes having any'desired relation to each other, and in the drawingsl have represented themas arranged to deliver nails in the form of a heel and as held by a block,

f which may act simply to hold the end of.

the tubes or additionally as a nail-holder, in which case it will be provided with a movable hole-covering plate, f

It will be seen that the nails as they are made are delivered directly from the nail pointing and severing devices to the passages of the distributer-that is, there is no transfer or carrying of the nails between these points. They drop by gravity upon theoperation of the severing devices immediately through the threats or passages and holes in the tubes.

The nails may be conducted to the naildrivihg devices by the tubes F, as describedin my patent, No. $116,007, dated August 3,

1886; or they may be taken from the lower ends of the tubes by means of a nail-carrier, G, in which, case I prefer that the nail-carrier be automatically moved by a cam, g, in time to act in unison with the nail making and driving devices; and H represents the templet through which the nails are driven, h the also with the gear m on the shaft a.

gang of nail-driving devices, and h the last or work-support.

The shafts carrying the nail pointing and severing devices are represented in Fig. 5 as connected with each other in the following manner: The shaft a is the shaft which carries the driving-pulley and clutch. (Not shown.) This shaft has a gear, on, which is connected by the gear-wheel m with the shaft a, and the gear 021- also meshes with the gear m upon the shaft a and this gear on meshes The shaft a also has a gear, m, which engages the gear m on the shaft a. 'The shaft a has a gear, m, which engages the gear m on the shaft (L The shaft has a gear, m which engages the gear on" on the shaft a and the shaft a has a gear, m which engages the gear m on the shaft a. It will thus be seen that the power is communicated from the shaft a directly to the shafts a a and through the gearm to the shaft a. The connecting-gears m m m m are upon the same vertical line. The shaft a is geared to the shaft to by the gears m m, the shafts a a are geared together by the gears m m", the shafts a a are geared together by the gears m m and the shafts a (dare geared together by the gears m m I11 operation the wires are simultaneously fed by the feeding devices to the nail pointing and severing devices in one full revolution of the machine made. This forms upon the ends of the wires and severs therefrom as many complete nails as there are wires used, and the nails thus severed immediately drop without being transferred or carried through the passages of the throat and distributer to the nail-driving devices or to a carrier which transfers them to the driving devices. It will thus be seen that the nails can be made in gangs or groups of any desired number rapidly as they can be driven, as the nailmaking devices can make a full revolution as quickly as the drivers of the nail-driving devices can make a full reciprocation.

Of course it is not necessary that the nail pointing and severing devices be arranged upon two lines, as I have specified, although for compactness and cheapness of construction I prefer this organization.

Heretofore in machines of this character the nails were delivered from the nail-making devices to a movable nail receiving or severing block interposed between the distributer and the nail-making devices, and which block received nails as they were made, and by this movement advanced a number of holes to a given throat or passage, so that a number of nails were made and delivered in successive order from each wire; or, if such were not the case, the receiving-block was used to transfer the nails from one position to another in relation to the nozzles through which the nails were delivered and the nail-distributer. By the present invention the nail receiving or severing block is entirely dispensed with and the nails are delivered directly to the passages of the distributer. This necessitates that there should be as many nail-making de vices as there are nails in any one gang or group, and that each nail making device should have a separate conducting-tube to convey the nail to the carrier or place where it is driven. Moreover, by this organization I am enabled to obtain all the nails of a gang or group by one revolution of the machine or rolls, so that a gang or group can be very quickly formed, while the machine may be run at a comparatively slow rate of speed.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination of a gang or number of nail-making devices each of which is adapted to make but a single nail of the entire gang or group required, and which are simultaneously operated, with a distributer having a hole or passage for each nail-making device and arranged to receive the nail from it without transfer as it is delivered, substantially as described.

2. The combination of a number of nail pointing and severing devices of the character specified, mechanism for feeding the nailstock thereto, a stationary distributer the passages of which are connected directly with the throats or passages through which the nails are discharged from the nail-making devices, and stationary tubes orblocks in which the throats or passages are formed, an automatic nail carrier or transferrer, and the naildriving devices, substantially as described.

3. The combination of devices for simultaneously making a gang or group of fastenings at one revolution of the machine, comprising the shafts a a (l a a a a a arranged in two lines and in relation to each other, as specified, and carrying nail pointing and severing devices, and the nail-stock-feeding devices, substantially as described.

4. The combination of the two pairs of shafts carrying the nail-pointing devices I) b and nail cut-offs b with the cams or projections b the cut-offs being arranged in the outer roll of each pair and the cams or projections at the outer side of each shaft, whereby each set of course is made accessible, substantially as described.
